Transcendence.
The word was packed with many different meanings. It held a lot of connotations.
It also featured prominently in many religions. The notion that humans were able to transcend their humanity and mortality was a popular notion. Who didn't want to shed their weak and boring human existences in order to become a powerful god or other supreme entity?
The Ylvainan Faith centered around it, and so did hexism! Many other religions constructed myths where the faithful would be rewarded for their piety by giving them an opportunity to transcend into a higher existence.
Ves thought that all of these promises were false. The faiths merely dangled imaginary rewards in front of the faces of gullible believers in order to incentivize them to act in a manner that served the interests of the charlatans who perpetuated the delusions.
